Zhongruan  is a 4-strings plucking instruments played by a plectrum, or by using two acrylic fingernails that are fixed to the fingers with adhesive tape like the pipa’s plectrums. The daruan is a bass instrument, and the zhongruan is a ‘tenor’.  It is held on the lap vertically, the fingers of the left hand press the strings onto the fret. The fingers of the right hand pluck the strings similar to the pipa but only with two fingers. Both instruments are most common instruments in Chinese orchestras due to its easily blending tone colour.  G-D-A-e
